Boot into the BIOS. "No bootable devices found" and similar errors often occur when the boot order is wrong. To fix it, boot into the BIOS. Start by shutting down your PC. Press the Power button to boot it up. Some PCs allow you to enter the BIOS by holding down Shift while your PC boots up. Most computers have a dedicated button you press on the keyboard to enter the BIOS during start-up. It's different from one computer manufacturer to another, but it's usually. F1, F2, F3, F10, F12. Del, or Esc.
- Alternatively, boot into the BIOS using the Windows Recovery Environment (WinRE). You can access WinRE using a Windows Recovery drive or by using the following steps:^{[1]XResearch source}
  - Shut down your computer.
  - Press and hold the Power button to boot up your computer.
  - Press and hold the Power button immediately (when you see the manufacturer's logo) to force it to shut down again.
  - Repeat 3 times.
  - Press the Power button to boot up your PC and allow it to boot into WinRE.
  - Select Troubleshoot.
  - Select Advanced Options.
  - Select UEFI Firmware Settings.
  - Select Restart.
The BIOS is different for each manufacturer. Normally, you will see a menu called "Boot," "Boot Options," or similar at the top. Use the arrow keys on the keyboard to navigate to this menu and press Enter to select it.

Put your computer's main drive first in the boot order. Change the boot order so your computer's hard drive (usually the "C:" drive) boots first. Make sure USB drives or CD/DVD drives are set to boot second.
- Alternatively, if removable or optical drives are first in the boot order, make sure you don't have any flash drives or CD/DVD/Blu-rays inserted. If you do, your computer is trying to boot from that instead of your hard drive. Remove the disc or flash drive, then reboot your PC.
- If you're intentionally trying to boot your PC from the connected flash drive or disc, you may need to make a new one.

Save and exit the BIOS. Your computer should boot into Windows from your hard drive.
- If you still get "No bootable devices found," continue to the next method.

- Alternatively, if you don't have a recovery drive, use the following steps to access WinRE:
- Shut down your computer.
- Press and hold the Power button to boot up your computer.
- Press and hold the Power button immediately (when you see the manufacturer's logo) to force it to shut down again.
- Repeat 3 times.
- Press the Power button to boot up your PC and allow it to boot into WinRE.
